The Independent State of Samoa signed the Mine Ban Treaty on 3 December 1997 and ratified it on 23 July 1998, becoming a State Party on 1 March 1999. Samoa has never used, produced, exported, or imported antipersonnel mines, including for training purposes. Samoa believes that existing legislation is sufficient to enforce the antipersonnel mine prohibition domestically. Samoa submitted its fourth Mine Ban Treaty Article 7 report in 2008, but has not submitted subsequent annual reports.

Samoa did not attend any Mine Ban Treaty meetings in 2010 or the first half of 2011.

Samoa is not party to the Convention on Conventional Weapons.
